Stupid fridge question

[ffutures]

Wearing my mad scientist hat again...

Just had the fridge-freezer delivered and they told me it has to sit for three hours before plugging in "because they don't use CFCs any more."

I knew that CFCs were banned, but I hadn't thought about what replaced them and why it would need so much longer to stand. I know that early fridges used ammonia, have they gone back to using that or is it something else?

Update Got home - fridge appears to be pretty cold, ditto freezer, so presumably working OK. I'll bung some frozen food in a little later, once I've checked the temperature. Now where did I put the freezer thermometer.

later Minus 18 - should be OK.

It's nothing to do with the CFCs, its been a problem for Freezers pretty much forever. The issue is more to do with how the collant settles in the compressor. You need to make sure that the compressor is full of collant and there are no airbubble or other gaps before turning it on otherwise you could dramatically reduce the efficiency of your freezer and the life time of your freezer.
